The LMV116/LMV118 are low voltage, 45MHz, rail-to-rail output operational amplifiers with shutdown option. They offer high speed and low voltage operation, as well as micro-power shutdown capability. The output voltage range extends to within 20mV of either supply rail, making them suitable for low voltage applications. Despite a low supply current of 600µA, the output current capability is maintained at ±20mA for driving heavier loads. Through a combination of process enhancements and design architecture, important device parameters such as bandwidth, slew rate, and output current remain relatively independent of the operating supply voltage. The LMV118 also provides shutdown capability with a turn-off current of only 15µA. The turn-on and turn-off characteristics are well-behaved with minimal output fluctuations during transitions. This allows the part to be used in power saving mode and multiplexing applications. The miniature packages (SOT23-5 & SOT23-6) further facilitate the adoption of these low power high speed devices in applications where board area is at a premium.
This document is a datasheet for the LMV116 (single) and LMV118 (shutdown) operational amplifiers from National Semiconductor. These devices feature a low voltage operation starting at 2.7V, a bandwidth of 45MHz, and a rail-to-rail output swing within 20mV of the supply rails. The LMV118 specifically includes a shutdown capability to reduce supply current to 15pA.
